Browser Fingerprint & Privacy Inspector Everything This Page Can Learn About You
See your browser fingerprint and every signal a website can read from your browser, ranked by how much each one identifies you. Includes opt-in IP address, VPN, Tor and private browsing detection.
Measuring how far this browser stands out from the crowd.

Your public IP is only visible to a server, so this check sends one request to iqverse.net. The response is rendered here and nothing is logged or stored.
Headers your browser sent
These travel with every request before a single line of JavaScript runs. Client hints under Sec-CH-UA describe your device, and Accept-Language repeats your locale.
Reducing your fingerprint
Individual rows carry a "Defence" line where one exists. Four strategies do most of the work, in descending order of effectiveness:
- Use Tor Browser. It blocks canvas, normalises fonts, pins the time zone to UTC and letterboxes the window so every user reports the same values.
- Use Firefox with privacy.resistFingerprinting enabled. It covers canvas, audio, WebGL, time zone and core count in one switch, at the cost of some site breakage.
- Blend in rather than stand out. Skip Do Not Track, trim your language list to one common locale and leave the user agent alone. Rare settings identify you.
- Keep a VPN and the browser consistent. Match the browser time zone to the exit country and disable WebRTC, or the mismatches on this page give the tunnel away.
How to read this
Entropy measures how much a signal narrows you down. Every bit halves the crowd you hide in. Around 33 bits is enough to single out one person on Earth, so the total is capped there. Real trackers reach a lower effective number because signals overlap, but the ranking still shows which ones matter.
The fingerprint ID is a SHA-256 digest of the stable signals only. Each row says whether it feeds the ID or varies per session. Values that shift between page loads, like window size and network speed, are excluded so the ID stays the same when you reload.
The return visit card stores that ID in this browser's local storage, and nowhere else, to show how well the fingerprint survives across visits. That is the whole trick behind cookieless tracking. Press "Forget this record" to delete it.
Private browsing and Tor detection are heuristics, not proof. They read side effects like storage quota limits and spoofed values, so a full disk or a hardened browser profile can push them either way. The Tor verdict only becomes certain once the IP check confirms the request came from an exit node.
Everything on this page is computed in your browser and nothing is uploaded, with one exception you control: the IP and VPN check needs a server to see your public address, so it sends a single request to iqverse.net when you press the button. That response is rendered here and never logged or stored.
